ROLLER AND BONNET ATTACHMENT FOR PLANlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 317,379, dated May 5,1885.

Application filed February 27, 1885. (N model.)

To all whom it may concern:

Be it known that I, DENNIS LANE, a citizen of the United States.residing at Montpelier, in the county of Washington and State ofVermont, have invented certain new and useful Improvements in Roller andBonnet Attachments for Planing-Machines, and I do declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being bad to the accompanying drawings, and tothe letters and figures of reference maked thereon, which form a part ofthis specification.

This invention relates to an improved roller and bonnet attachment for atraveling'bed planing-machine of the class adapted to plane severalnarrow boards of uneven thickness at one time.

The invention is clearly illustrated in the annexed drawings, whichrepresent so much of a planing-machine as is necessary to anunderstanding of my improvements.

Figure 1 is an end view of my improved roller and bonnet attachment forplaning-machines, the rotary cutter-head and a portion of the travelingbed being shown in dotted lines. Fig. 2 is a front 'view of thesectional roller and sectional bonnet with theirsupporting-framefshowing the manner of mounting the same in the frame ofa planing-machine. Fig. 3 represents a side or end view and a rearelevation of one section of my improved roller and bonnet attachment fortrav cling-bed planingmachines.

Like letters of reference designate like parts in the several views.

The frame A of the planing-machine supports a transverse bar, 13, towhich is attached a shaft, 6, on which are closely mounted thepressure-arms C 0, each of which carries a section of the sectionalbonnet D, and also one of the yielding rolls forming part of the sectional roller E, as shown in Figs. 1, 2, and 3. Each section of thebonnet D is pivoted at c in one end of the roll-carrying arm 0, and isformed with the necessary. curve to overhang the cutter-head, as shownin Fig. 1.

By reference to Fig. 3 it will be seen that each pivoted or hingedsection of the bonnet D is formed on the cutteuhead side with shouldersd d, that correspond with similar shoulders formed on thesupporting-arms O, and so prevents the pivoted shield or bonnet fromdropping onto the cutterhead, and yet permits each section to be turnedso as to uncover the cutter-head when required, as shown by dotted linesin Fig. 1. The forward or feed end of each arm (3 is connected with thebar B byavertical bolt, (2, the upper end of which projects above thebar B, and is surrounded by a spiral spring, f, confined by anadjusting-nut, g, by which the tension of the spring is regulated. v

The operation of my improved sectional pressure roller and sectionalbonnet attachment for planing-machines will be readily understood.

It will be observed that by forming the bon net, shield, or'hood D insections to correspond with the sections of the pressure-roller E, andmounting each section of said bonnet and roller independent of itsfellows, the bonnet is made capable of a vertical movement in unisonwith each section of the yielding pressure-roller, thereby obviating allliability of jar or strain, and facilitating the action of the machinein simultaneouslyplaning a num ber of boards of unequal thickness.

Having thus described my invention, what. I claim as new, and desire tosecure by Letters Patent, is

In a planing-machine, the combination of the frame A, transverse bar B,shaft 1), pressure-arms O O, mounted on said shaft, the vertical bolts e6, provided with nuts g, and springs f, whereby the bar B and arms 0 arecon nected, the pressure-roller E, formed in sections, each of which isjournaled in one 0! said arms, and the bonnet D, also formed insections, each of which is mounted in one of said arms, substantially asshown and dc scribed.

In testimony whereof I adix my signature in presence of two witnesses.

' DENNIS LANE.
